When the PRT asked for a strategic bomber, aircraft designers turned not to other bombers for inspiration, but instead to a near invincible aircraft with a spotless combat record; the SR-71 Blackbird. With minimal wings, no tail, and thrust vectoring engines, the Shoe Box is capable of flying at up to Mach 2.7, and has a height ceiling of 80,000. However, it has to be below Mach 2 & at most at an altitude of 55,000 feet to safely release its payload of either bombs or a cruise missile. Should a SAM be launched against it, it can use it's thrust vectoring engines to out maneuver it.

Here is the SB-1 inside it's hanger.

Engines can move to Thrust Vector.

Bomb bay closed.

Bomb bay open, with a nuclear cruise missile inside. When no other option for victory is presented, the PRT believes strongly in the "If I can't, no one can" philosophy.

Side by side with the F/A-1 Hummingbird.

Started at noon, it's up by 4 XD should hold the line while I make a better version. Enjoy!

Couple more nitpicks (sorry if I come off critical, but I am thorough with military tech).
To maintain high accelerations beyond mach 1, you ought to have the wing root (where it's mounted) be farther forward (but don't increase length). Make the leading edge sweep back at a faster angle by bringing it forward. Again, don't sell yourself short. You can drop bombs from 50,000ft+ and supersonic. Lastly, There is no outrunning SAMs. Some SAMs can fly at over mach 4.
